GAS: ability target data from actor return value ()

Recently, I have been using the GAS to test some ideas. I have used the “Ability Target Data From Actor” node in the blueprint to construct target event data for the ability to deal with.

But the return value of this node is always ()

I can see the input “Other Actor” is the blueprint class of the character.

I do not have a clue what I have done wrong

Were you ever able to sort this out? Running into the same issue.
